JAMES A. BARCLAY, OF INDIANAPOLIS, INDIANA.

SPECIFICATION forming part of Letters Patent N0. 741,212, dated October13, 1903.

Application filed January 5, 1903. Serial No. 137,759. (No model.)

To all whom it may concern/.-

Be it knownthat LJAMES A. BARCLAY, a citizen of the United States,residing at Indian apolis, in the county of lllarion and State of Indiana, have invented new and useful Improvements in Railway-TrackScales; and I do declare the following to be a full, clear, and exactdescription of the invention, reference being had to the accompanyingdrawings, and to the letters and figures of reference markedthereon,which form a part of this specification.

My invention relates to scales that are adapted for weighing loads onvarious large vehicles and the vehicles themselves, as well asrailway-cars and their loads, and it has particular reference to thefoundation-walls and framing and the supports for the levers that carrythe platform in scales of this charaeter.

The object of the invention is to provide an economic construction inweighing-scales that may permit of comparatively shallow and short andnarrow foundations, so that a saving in excavations and masonry may beeffected, and also in order to be able to locatescales where deepfoundations may be impracticable.

My invention consists in weighing-scales having the principal leversthereof supported in a novel manner by the coping of thefoundation-walls; and it consists also in the novel parts and in thecombination and arrangement of parts, as hereinafter particulardescribed, and pointed out in theclaims.

Referring to the drawings, Figure 1 represents in a fragmentarylongitudinal vertical sectional view a scale construction substantiallyin accordance with my invention; Fig. 2, a transverse vertical sectionalview of the same; Fig. 3, a transverse sectional View of thecoping,showing a bracket attached thereto for supporting a lever; Fig.4;, a fragmentary transverse view showing the lever to which thescale-beam may be connected; Fig. 5, a fragmentary side elevation of acoping and sectional view of the pit wall, showing a bracket attached tothe coping in a pocket or recess in the wall; Fig. 6, a top plan view ofthe pit or foundation walls showing the pockets therein foraccommodating the supported ends of the principal levers; Fig. 7, afragmentary longitudinal vertical sectional supporting the mechanism.

view of the scale as constructed with a single platform and pittherefor; Fig. 8, a transverse vertical sectional view in a plane nearthe center of the pit, showing the supports for a dead rail; Fig. 9, afragmentary longitudinal vertical sectional View showing supports for adead rail; Fig. 10, a transverse vertical sectional view showing detailsof stand-support for a longitudinal lever; Fig. 11, a top plan view of alongitudinal lever, and Fig. 12 a fragmentary sectional detail viewshowing arrangement of platform-braces.

Similar reference characters in the drawings designate like parts.

In practically carrying out my invention the scales preferably have twosections separated a suitable distance, with the levers of the twosections connected together and with one beam, so that two platforms arearranged only at the proper places to accommodate the two trucks of acar, leaving a dead track between the platforms that either truck of thecar must cross when the car is being placed on the scales, this planeconomizing largely in structural expenses. A continuous pit and asingle platform, however, maybe employed if preferred.

In the drawings illustrating double-platform construction, A and I)designate two main pits, and c the natural earth section between thepits. A foundation a is provided, usually of concrete, which may extendover the bottoms of the pits if desired, upon which the side and endwalls are built for Portions of the foundations and walls are omittedherein in order to avoid obscuring less obvious parts of the scales. Theend walls I) b have pockets D D in their inner faces, which are open atthe tops of the walls and they are situated midway between the sidewalls. The pits A and B are connected by a narrow walled pit d, which isconnected by a narrow walled transverse pit e, the ends of the pit d inthe end walls Z) b serving as recesses in which to hang levers, besidespermitting the levers to reach to the pit e. The side walls f havepockets E E,similar to the pockets D D',which are arranged near the endsof the pits A and B, opening thereto. Upon the walls of the pits A and Bmetallic copings F F G G are set, so as to be close to the pits andextend ing over the pockets in the walls, the copings being preferablycomposed of I-section form of structural steel or iron, their ends beingsuitably connected together at the corners of the pits.

Brackets II are secured to the coping members above the pockets in thewalls and portions of the brackets extend into the pockets. Each bracketpreferably has an arm 7L ex tending to the top of the wall at the rearof the pocket, and ears i of the brackets extend below the coping intothe pockets, suitable pivots j being mounted in the ears.

In the pockets E E links are hung on the pivotse' and loops Z are hungon the links and pivotally support the transverse levers I I, whichextend nearly half-way across the pits to other levers. In the pockets DD loops or are connected to the pivots t and pivotally supportlongitudinal levers J J, the latter preferably having bifurcated ends ofthe usual forms, as indicated in Fig. 2. The movable ends of the leversI I, that are situated near the end walls I) b, are connected by loopsin the usual manner with the levers J J. Loops n are connected to thepivots 71, that are supported by means of the copings F F and pivotallysupport longitudinallevers K K in the pit cl, bothlevers K Kbeingsupported intermediately of their ends. One end of each lever K andK is connected in the usual manner by means of loops to the movable endsof the levers J J, and near these connections they are similarlyconnected by means of loops to the movable ends of the levers I I, thatare hung near the end walls Z) I). The opposite ends of the levers K Kare connected by means of suitable loops to the inner end of the pivotedlever N in the pit (Z, which lever extends into the pit e for connectionwith the beam, as will be understood.

The platforms are pivotally mounted upon the levers I I in a suitablemanner, andthey comprise each a pair of horizontal beams L L, extendingalong the inner faces of the side walls of the pits A and B above theirsupporting-levers, the beams having suitable transverse braces M and mayhave anglebraces p secured thereto. The beams preferably have Woodenties q or a floor thereon, upon which are secured the track rails O, inalinement with the rails O on the ground section 0 and also with therails leading to the scales. If desired, dead rails P P, forming arun-around track, may be provided in the usual manner, one rail beingplaced upon a coping G or G and the other upon pillars rising from thepits, as will be hereinafter described.

hen a single continuous platform is preferred, it may be mounted on thesame system of levers as those upon which the plural platforms aremounted or upon other systems of levers, and the earth section C will beeliminated and walls I) Z) will not be required, and obviously thecopings F F will not be employed. Usually the platform in this case willbe about three times the length of one of the plural platforms. In lieuof the copings F F for supporting the levers K K the latter may besupported on stands Q, whichmay be suitably supported 011 pillars, butpreferably on beams r, extending across the pit, and the beams may becentrally supported by pillars s. lVhen the run-around rails P I areused, one of the rails is bolted to the flanges of the I-section copingat one side of the platform, and the companion rail is supportedindependently of the platform at the top thereof, pillars t in the pitbeing employed for the purpose, and preferably the rail is connectedwith the pillars by means of I-beams It, resting on the pillars andposts S, secured on the beams and extending through apertures a in thefloor q. The braces M may extend between pairs of the posts S. Tie-barsT may be secured to one of the copings and also to the beam R, extendingthrough an opening 1) in the platform beam, as in the beam ll. In somecases the levers K K are offset near their central portions, as in Fig.1, and they may be straight, as in Fig. 7. The central portions thereofare usually open, as shown particularly in Fig. 11, thus having doublebars to 10, between which. the pivot-pins 'g y/ extend. The pin 3 isconnected by loops 1 and 2 to a pivot-pin 3 011 the top of the standQ,w-hieh supports thebeam. The plural platform-sections and theintervening dead section may each be about fourteen feet in length, thusproviding compact durable construction, in which the saving in cost willbe apparent.

In practical use the scales may be operated in the usual manner, and itwill be found that the copings, together with the arms 7L of thebrackets II resting upon the walls, will provide stable supports for thelevers that are thus substantially supported by the copings.
